Carbonate rocks are a class of sedimentary rocks composed primarily of carbonate minerals. The two major types are limestone and dolomite, composed of calcite (CaCO₃) and the mineral dolomite (CaMg(CO₃)₂) respectively. Chalk and tufa are also minor sedimentary carbonates. Two types of sedimentary rock: limey shale overlaid by limestone. ... Ball-and-stick model of the carbonate ion, CO32− For other meanings, see Carbonate (disambiguation) In chemistry, a carbonate is a salt or ester of carbonic acid. ...

The Needles, situated on the Isle Of Wight, are part of the extensive Southern England Chalk Formation. ... Tufa is the name for an unusual geological formation. ...

Calcite can be either dissolved by groundwater or precipitated by groundwater, depending on several factors including the water temperature, pH, and dissolved ion concentrations. Calcite exhibits an unusual characteristic called retrograde solubility in which it becomes less soluble in water as the temperature increases. Solvation is the attraction and association of molecules of a solvent with molecules or ions of a solute. ... Missing main definition------ someone add if you know it please. ...

When conditions are right for precipitation, calcite forms mineral coatings that cement the existing rock grains together or it can fill fractures.

Karst topography and caves develop in carbonate rocks due to their solubility in dilute acidic groundwater. Cooling groundwater or mixing of different groundwaters will also create conditions suitable for cave formation. Karst topography occurs when a landscape is marked by underground drainage patterns. ... For discussion of land surfaces themselves, see Terrain. ... For other uses, see Cave (disambiguation). ... Solubility is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent. ... For other uses, see Acid (disambiguation). ...

Marble is the metamorphic carbonate rock. Rare igneous carbonate rocks exist as intrusive carbonatites and even more rare volcanic carbonate lava. For other uses, see Marble (disambiguation). ... Quartzite, a form of metamorphic rock, from the Museum of Geology at University of Tartu collection. ... Igneous rocks are formed when molten rock (magma) cools and solidifies, with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks. ... Pluton redirects here. ... Carbonatites are intrusive igneous rock structures with more than 50% carbonate content, many of which contain distinctive abundances of apatite, magnetite, barite, and fluorite, that may contain economic or anomalous concentrations of rare earth elements, phosphorus, niobium, uranium, thorium, copper, iron, titanium, barium, fluorine, zirconium, and other rare or incompatible...
